About the role

You'll help shape where the product goes next — working closely with engineers, designers, and founders to design, build, and iterate on core parts of the platform. You'll own projects end-to-end: from scoping and building to testing, shipping, and refining based on real-world user feedback.

We're looking for someone who loves crafting clean, fast, and intuitive user experiences, is comfortable with ambiguity, writes maintainable, high-quality code, and wants to contribute to the engineering culture.

• Proven ability to lead and deliver technically challenging, cross-functional projects
• Kotlin, TypeScript / React, PostgreSQL, Google Cloud
• Comfortable designing APIs, debugging complex systems, and writing tests

• Knows when to ship vs. when to refactor

Nice to have

• Startup or small-team experience
• Experience with B2B products like Square or Toast
• Experience with consumer apps like Cash App, Robinhood, and Coinbase

Details

• Work setup: in-person, five days a week (New York or Toronto) — no remote option
• Location: New York or Toronto
• Visa: open to H1B transfers and TN visas for Canadian candidates
• Meaningful equity
• Full-time
• Actively hiring several engineers for this role

We are looking for a Senior Full Stack Engineer who is comfortable working on high-load, distributed systems and making architectural decisions, not just implementing tasks.

At MMDSmart, you will work on a CPaaS/CCaaS platform handling messaging and voice communication at scale. This is not a typical CRUD product: you’ll deal with real-time flows, external integrations, billing complexity, and systems where design mistakes surface quickly in production.

You will be expected to take ownership from design to delivery and challenge assumptions when needed.

Since 2007, MMDSmart has been a leading supplier in cloud-based business communications, delivering game-changing IT products to businesses in over 100 countries. Our success is fueled by the inspiration and innovative ideas of our team members, encouraging their growth and impacting our Messaging andVoice solutions. These empower our clients to communicate more effectively with their customers. Don’t miss this chance to excel in a rapidly expanding tech company, where your potential and ambitions are not just recognized but celebrated.

What will you do at MMDSmart?

• Design and implement new platform capabilities across backend and frontend (not just “features” but system-level improvements);
• Contribute to architecture decisions in a microservices environment (Go-based services, event-driven patterns, APIs);
• Build and evolve React-based interfaces used by enterprise customers and internal teams;
• Work on integrations with external vendors (messaging providers, voice, billing systems);
• Investigate production issues in a high-scale environment and drive them to resolution—not just patch them;
• Participate in technical discussions, trade-off analysis, and system design reviews;
• Occasionally lead initiatives or own a domain end-to-end.

You are a perfect match if you have:

• 4+ years of real production experience as a Full Stack Engineer;
• Strong backend expertise with Go (3+ years), not just syntax, but concurrency, performance, and system design;
• Solid frontend experience with React + TypeScript (2+ years);
• Experience building or maintaining distributed systems / microservices;
• Good understanding of data modeling (SQL + NoSQL) and when to use each;
• Ability to debug complex issues across services (not limited to your own code);
• Comfortable working in an environment where requirements evolve and not everything is predefined.

Will be a plus:

• Experience with real-time systems, messaging, or telecom domains;
• Familiarity with event streaming (Kafka or similar);
• Experience with cloud platforms (GCP preferred);
• Exposure to billing systems or high-throughput APIs.

What you get:

• Work on systems that actually operate at scale and have real business impact;
• A team where senior engineers are expected to influence architecture, not just execute;
• Remote work.

Why do talents choose and stay at MMDSmart?
Embrace the opportunity to work in a company that cares about:

Your Wellness: Access to mental health programs, comprehensive medical insurance, and a sports card*.

Your Happiness: Enjoy the company of cool teammates, a friendly atmosphere, a strong mentorship, and a variety of bonuses & corporate gifts.

We are looking for a Microsoft 365 / SharePoint Developer to join our client, an established Israeli software company specializing in custom business solutions built on top of the Microsoft 365 ecosystem.

The company develops tailored business applications that help organizations digitize and automate internal processes. Their projects include helpdesk systems, HR platforms, approval workflows, internal portals, business forms, dashboards, document management solutions, and other operational tools built for enterprise customers.

We’re not necessarily looking for someone who has already built these exact types of systems. What matters most is a technically strong engineer who can design and develop complex business applications within the Microsoft 365 ecosystem.

Responsibilities

* Develop custom business applications using SharePoint Online and Microsoft 365.

* Build modern SPFx solutions with React and/or Vue.js.

* Design and implement integrations with Microsoft and third-party systems.

* Develop workflows and automations using Power Automate.

* Work with Azure services when required.

* Design scalable architectures for business applications.

* Troubleshoot and resolve complex production issues.

* Translate business requirements into clean, reliable, production-ready solutions.

* Take ownership of features from architecture through delivery.

Requirements

* 3+ years of experience developing solutions on Microsoft 365 / SharePoint.

* Strong hands-on experience with SharePoint Online and SPFx.

* Strong knowledge of React and/or Vue.js.

* Experience with SharePoint REST APIs, Microsoft Graph, and SharePoint APIs.

* Solid experience with Power Automate.

* Experience with Azure services.

* Experience integrating external systems and APIs.

* Strong debugging and problem-solving skills.

* Ability to work independently with minimal supervision.

* Upper-Intermediate English or higher.

Nice to Have

* Experience with Power Apps.

* Microsoft Teams integrations.

* Azure Functions.

* CI/CD for SharePoint solutions.

* Experience designing enterprise business systems.

We’re looking for someone who is not just a frontend developer, but a strong engineer capable of owning complex SharePoint-based solutions from architecture through production.

The role

You'll be a hands-on engineer working across our whole product: the Flutter consumer app, the AI coach and publishing platform, and the Supabase backend they share. You'll own features end to end - scoping, building, testing, shipping, and monitoring them - with a high degree of autonomy and trust.

We're hiring at mid level, deliberately: as the business grows, we want this person to grow into a senior technical leader on the product. You'll get increasing ownership of architecture decisions, internal tooling, and engineering practices as you demonstrate you can carry them.
 

What you'll actually work on

• Consumer features in the Flutter app (iOS, Android, web): the coach chat experience, the audio player, onboarding and subscription flows.
• The AI lifestyle coach - our flagship AI feature, and real agentic engineering: an LLM coach with selectable personas, long-term memory (it extracts and recalls what matters to each reader across sessions), and a toolbox of actions - recommending books, pulling chapter content, saving daily intentions and takeaways, tracking goals — with safety guardrails and context management (compaction, resumable sessions) built in. 
• The AI publishing pipeline — the machine that turns a raw book PDF into a polished, multi-language product: parsing → LLM summarization → translation → AI cover generation → ElevenLabs text-to-speech with audio stitching, orchestrated as durable, crash-safe workflows
• Backend work in Supabase: Postgres schema and migrations, Deno edge functions (payments webhooks, notifications, the coach backend).
• Internal tooling: publishing scripts, the LLM eval harness, developer-experience improvements. If a manual process annoys you, you're empowered to automate it.
• CI/CD: we run GitHub Actions, Codemagic mobile builds, and migration-validation pipelines — you'll help keep releases boring and frequent, and raise the bar on testing and deployment practice.
• AI-assisted development is how we work: we use AI coding tools (Claude Code and similar) as a core part of feature development, and we expect you to use them well — including knowing when not to trust them.
   

What we're looking for

These are our must have requirements. If you meet most of them, please apply.

• 4+ years of professional software engineering experience, including features you've shipped to production and supported afterwards.
• Strong in our two main stacks - Flutter/Dart and TypeScript/React
